You can only get the pumpkin batkini through the Deader than You tour- but you can get batkinis regularly in a bunch of other colours as well (p.s. they come with tokens, too).
But anyway- bikinis with bats on them! Bits of colour peek out from underneath black bat wings. Sculpted string ties at the neck and back, and either hip.
(Lazy Places tentacle lip ring on all the girls of the fatpack ♥; hair: Schadenfreude Tish, Jinx, BP* okappa, Schadenfreude Thom, Augustine, Cinder, Clawtooth by Clawtooth special edition of Electric Slide; all skins Schadenfreude Alabaster Lanwidered Smudged Black)
The batkinis are out on the floor in the elephant, for your spooky skinny dipping in the moonlight pleasure.
